Hi. I am new to LightBurn and engraving. I have had much success engraving designs on slate but I cannot get a grasp of engraving pictures. I have an OMTech 55 watt. I do not know my “controller” or “firmware”. I am still on my 30 trial of Lightburn.
This first picture is the original photo.
Here is the result using the “adjust image” settings above. Ignore the black circles on the corners. Not wanting to waste product I am using the front and back of the slate and those are the marks from the corner pads I removed.
Thank you for this. Please update and share the settings used as well. Power, Speed, and the image cut settings. I know you said you used “the “adjust image” settings above.” but I’d like to confirm what you have set there as well.
I might use a different scrap material to test getting an image to produce as you like, prior to testing on slate. You can remove your testing from the slate using a sander (search hot to do this on this forum), but that takes time. Once you have a process that works for you, testing on an inexpensive material, use that to dial in for a specific material.
The image showing the flag, looks like you have some mechanical issues, skipping, loose belts or some parts of the gantry system not snug, and moving when changing directions. Something is not correct, producing these doubling artifacts. I would take a once over to ensure all components are moving smoothly, without binding, snug and working correctly. You may need to dial this hardware in a bit to get the best possible results.
